The groupexplores these issues as integrated problems. In motivation of thisapproach, note that proper perception of shape is important in design,and proper calculation of first and second order geometry propertiesare critical for manufacturing. Without accurate lighting models andcomputational methods for rendering shape, perceptions of shape can bedistorted. Without proper methods of transforming a piece of metal toa final shape, the final manufactured object can be wrong.<P>The group is also actively researching issues related to the ScientificVisualization of data arising from a variety of applications. Thisinvolves the development of new algorithms and interfaces for renderingboth realistic and abstract images and interacting with the resultingvisual representations.<P>As early users of our results, affiliated prominent projects in robotics,vision, and engineering design serve as sources of relevant research problems.
